To .allvwhom it may concern:

Be it known that we, WALLACE D. Kiar- BALL and CHARLES G. MORTTMER', both citie zens of the United States, residing, respectively, at the city, county, 'and lState of `New York and at No. 123 South Parkway, East Orange; Essex county, New Jersey; have invented new and useful-Improvements in Spliced Joints for Bale-Bands, of which the following is aspecication. 1

This invention relates to spliced joints or fasteners for bale-bands and box-straps, and has for itsV object to provide a strong and durable joint which may be readily applied to the bands or straps and which will permit of the ends of the'band Or strap being drawn past each other to tighten the Aband or strap around the bale or .box on which it isused. -1` l A further object-ofthe invention isto provide a joint of this character invvhich the appliedpiece which holds theV ends of the bands togetheris of simple construction and may be made 'of lightsheet Ymetal by/a series Ofstamping'or similar operations sofas to be capable of "manufacture upon automatic machines'in large quantities at very lowcost., n 1 p In the accompanying `drawings we have illustrated" several :formsof our improved joint, allfembodying the same essentialfeatures.v In the said drawings:

F igure` l is a perspective' view showing one form1 of our invention;

Fig. `2 is a longitudinal sectional viewV ofy the joint shown in Fig. l;

Figs. 3 and et are'sectionalviews on oorj respondingly numbered lineslof` F ig. 2;

Fig. V5 is a" longitudinal sectional view showing a slightly modified form of joint;

Fig. 6 is a similar-view showing a further modification of the joint; 1 Fig. 7 is a perspective view of the sheet metal bart by which the ends of the strap are connected in carrying out our invention- -Y f Figs. 8 and 9 show iny elevation and lon# gitudinal section respectively a further modification of our bale tie, and' Fig. 10 is a perspective view of the modi-y fication.

Referring to the drawings, 1 indicates the sheet metal part by which the-ends 2 and 8 of the strap or band are connected.`- The part l comprises essentially a flat tube of sheet'n'ietalpreferably of about the weight middle of its length the sleeve is'k cutaway on. the side having the seam 4, asindicated at 5, and in the wall oppositetlie cut-away portion there is formed an offset or depression 6 which serves the double purpose l of astop for one end of the band anda 'cam lfortlie other-'end of the band to deiiect it out through the cut-away portion ofthe wall 'of the tube to permit :the strap to vbe tightened on the box or 'bale before the strap and f,

tube are crimped, as shown at 7. l

In' applying the bands or straps to the boxes or crates to be bound,l the tube 1 will be slipped over one endofthe strap until theendof the strap enga'ges'the middle ofset: The strap willvthen belplace'd'aroundv tlie box and the other end of the strap i 'thrust through the Opposite end of thetube f until it engages the offset 6 bywhich it will,

upon continued thrust applied'to the strap,

be deflected' to project out of the cut-away' portion of the tubeor` sleeveand under the sleeve,t asshown infF 1g. 2.

.Afterfthe band is ldrawn as ytight as' may i be easily done by hand a stretching tool is` applied to the ends of theband on each side of the sleeve l, and the ends drawn toward each other until thefband tightly encircles the boX, thereby thrusting thev end 2 of thev strap farther underi'the opposite rend of the tube.V While the band is held tight with the stretching tool acrimper lis Aapplied to each end ofthe tube,`crimping both Walls of the tube and the intermediate strap together to thereby securely' attach each end of'the strap to itsV portionV of the tube or sleeve l.

VIii-Figs. 1a`nd12' we have shown but a single crimp at each end of the sleeve Aand with stock ofthe character usually employed y for the strap land sleeve, a single crimp is stronger than'the metal of the strap itself. The sleeve is preferably made ofnietal of the same gage as the strap sothat the lmiddle part'of the sleeve will beat least as strong as the strap, in fact, with the edges of the sleeve left uncut in the manner shown in the drawing, a lighter metal may be used for the sleeve if desired, without reducing the strength of the binding.

Instead of the single crimp for each end,

we may prefer to use a tool designed to form a double crimp as indicated in Fig.V 5, or the strap ends-and sleeve maybe corrugated ltogether from end tol end of thev sleeve in the manner shown in Fig. 6. When the corru- `gations of'vFig. Gare used, each individual Crimp OTICOTIUgaOIl may-be less lacute than the singlet or:V double crimp shown in the other views, and may be made by a corrugating roller or similar device.

In Figs. 8 and 9 We have illustrated a further modification of ourV invention in which the fastening element is made from a flat stripv of metal' by .the single operation of a cutting and bending die, and which `also admits ofjbeing very readily applied with- Y bethreaded betweenV the` oppositely bent 45, v the punching die instead; of coliipletel-yde'- out special-tools, vInthis form of fthe invention the-fastener is made of 'a `stripv 10 Y of sheet metal providedwith a seriesof transverse slotsextending along the middle of thek strip and terminating short of the edges as indicated at 11, the slots -being preferably formed by punching out narrow strips of 'metal instead of by simply slitting Vthe sheet.

By the. same operationthe sheet-may be Mbent as shown, thatis, each alternatestrip between two adjacent slots is bent Vdown below the :plane of the sheet togan extentsuf-V ficient to permit the 'end of the band to rlhe cross bar 12 at ythefmiddle of the length of the tie is providedwith a turned-V upedge 13 `formed by cutting the metal to form ,the opening between fthe middle cross bar and theadjacent cross bar en onegside around threeV edges only, so that the piecey ofnietal will be turned up by the action; of

A. tached from the sheet. lThe turned up edge shown. In applying this form of tie to the 13 acts ,as a st op tobeengaged by one end Vof the strap to be Connected when the end .is thrust between the alternate cross bars as bandit may, if desired, be first crimped on the end 145' ofthe-bandby-clipping the tie sheetr over Vthe end of theband until itengages the turned up edge 13 and then flat tening the oset cross bars12 vto corrugate the band, as shown more particularly in Fig. 9. After the -fastenerhas been'attache'd i end of thefastener.

to one end of the bandfor strap the strap will be placed aroundthe'box or bale and,V

its opposite end thrust through the yopen portion of thefastener with thelend of the strap projecting above or below the crimped This end ofthe fastener will then be flattened by hammeringl. A spliced joint comprising two jstrap operation with a suitable tool after the band is drawn tight, and effectively seal the two ends of the band together.

The band, however, may be attachedvv to the box at one operation in the' manner heretofore` ointed out in the alternate form of the device. Also, if desired, the turned 'up edge 13 may be omitted and both ends of the band thrust through the entire lengthl of the fastener in overlapping relatiomfand both bands and the fastener crimped'or corrugated together-byv a single flattening op-V eration.

We claim ends Ato be connected,- a -tube or sleeve hav ing different lportions j surrounding the two'V strap ends, each saidportionand its iii-7 gation' therein, said tube Vor sleevehaving a portion of its wallcut out on one-sideto permit one'end of thestrap to `,project therethrou h..

2. spliced joint comprising two strap. ends tof be connected, sleeve surrounding each 4of 'said' strap ends each strap end and .its inclosingsleevebeing corrugated to pre'- closed strap end having acrimp or corruvent withdrawal of said strap yend fromthe l sleeve, and anopening cut in the ,wall in c Y one side of the said sleeve to permit oneof said strap ends -to;project therethrough,

3. A `spliced vjoint comprising two-strapV ends to be connected, a sleeve surroundingA each of said `strap ends each strap end and',

its inclosingsleeve being wcorrugated to pre- V vent withdrawal offsaidstrap end from the sleeve, and an openingcut inthe Vwall linonefside of'said sleeve `toipermitone of said strap ends to project therethrough, and means for deflecting saidl strap end to cause Vit to projectfthrough'said opening.` 1 4. A. bale tie consisting of anat metalA tube of a size `to en`circ le the bale lband or strap, saidtube `hav-ing la `portion of one wall intermediate -its endcut away toallow the free end of onefstrap `to,project therethrough.` v .Q

.5. A bale {tie consisting of a ila-t metal tube ofasize to encircle thebal'e band or strap, saidjtube havinga portion .ofA one wall intermediate itsendjcutaway to allow the free'endofvoiievstraptoiprojectthere- Y dinal movement of thestrap ends with the free end of one strap .projecting throughv the side ofthe sheet finetalpiece and in over` lapped relation with the other strap end, but outside the sheet metal piece.

7. A spliced joint comprising two strap ends to be connected and a sheet metal piece having different portions surrounding the two strap ends, said sheet metal piece having a transverse projection in line with the end faces of the strap ends to thereby act as a stop to one strap end and deflect the 10 other laterally away from the sheet metal piece, the sheet metal piece and the portions of the strap ends surrounded thereby being crimped or corrugated together so as to prevent relative longitudinal movement of the strap ends.
